Variable Temperature Cryostat for Quantum Sensing of Materials Using NV Centers in Diamond
Abstract
NV magnetometers are quantum sensors that have shown tremendous promise in physics, chemistry, biology, earth and planetary sciences and more. Thus far most applications involving NV magnetometers have been ÔdemonstrationÕ type exploration of paramagnetic spins in sterile environments. Our single PI grant under the ARO is aimed to explore advantages of NV based magnetometry in real systems such as magnets and insulators. While some of this physics is already visible at room temperature other phenomena might require low temperature conditions where unwanted effects such as phonons are absent. The goal of this project is to set up a variable temperature diamond magnetometer operating between 5K and room temperature. This instrument will enable local exploration of magnetic properties of materials with fast turnover. This setup will take advantage of diamond nanowires that will be fabricated and placed on top of the system under study. Such wires allow high photon collection efficiency leading to exceptional magnetic sensitivity. The system will be integrated into an existing NV magnetometry setup that already has all the necessary optical and electrical components needed for a complete and state of the art operation. The construction and application of this experimental addon also provides excellent training in experimental quantum and condensed matter physics for undergraduate and graduate students and postdoctoral researchers.
